Can we let FSR and CLKR pins unconnected in McBSP SPI clock stop mode ?

Hi,

I want to use the C5509A McBSP in SPI slave mode. The FSR and CLKR pins are not used in this configuration.

I read in SPRU592E page 6-14 that "...The FSX pin is also internally connected to the FSR signal, and no external signal connections are
required on the CLKR and FSR pins."

Can I let both FSR and CLKR pins unconnected (floating) on my board ?

Best regards,
David
